Why do you need logistics and services companies?

Conducting online business is not as simple as it looks. It is a combination of a number of companies and units working in partnership in such a way that it appears to be conducted from one end. In fact e commerce companies have to take the help of warehousing and order fulfillment companies along with logistics and associated service providers to fulfill an order completely. Once the customer makes a purchase online, the order is transferred to the warehousing company and then to the order fulfillment company from where it goes to the logistics company.
